One of the properties that makes copper, Cu, useful for household wiring is its ability to conduct electricity. Which other element is most likely to conduct electricity?

Pitanje 21
21.

Which element group is typically shiny and good at conducting heat and electricity?

Pitanje 22
22.

Which characteristic does not typically apply to nonmetals on the periodic table?

Pitanje 23
23.

What two properties are typically associated with metals?

Pitanje 24
24.

Rank the folowing physical properties as Metals, Nonmetals or Metalloids. NO OPTION WILL BE USED TWICE. Pick whatever the BEST answer is for each physical property.

  • Gas at room temperature

  • Shiny with good luster

  • Good Conductor

  • Ductile

  • Semi-conductor

  • Roughly 7 elements on the periodic table

  • Malleable

  • A brittle solid at room temperature

  • High Electronegativity (only High)

  • Good Insulator

  • Low Electronegativity

  • Dull with poor luster

  • Metals

  • Nonmetals

  • Metalloids

Which two options best describe the appearance of most metals?

Pitanje 26
26.

Means a substance can be pounded or hammered into thin sheets or molded into shapes.

Pitanje 27
27.

The measure of ease at which an electric charge or heat can pass through a material

Pitanje 28
28.

Ability of an object to reflect light

Pitanje 29
29.

The tendency of a material to fracture or shatter under pressure

Pitanje 30

the way most metals can be stretched into a wire

Pitanje 31
31.

A material that keeps electricity or heat (or cold) from transferring

  • Always Exothermic when bonds form or break

  • Good Conductor

  • Contains atoms with a net charge

  • Soluble in Water

  • Low Melting & Boiling points

  • Brittle & Flammable

  • Covalent Bond

  • Ionic Bond

EXTRA CREDIT: Explain the three steps required to form an ionic bond. Make sure you state which substances (metals, nonmetals, metalloids) are involved, what happens to the valence electrons (and why) and what this causes the atoms to do.

  • use the terms high/low electronegativity, cation/anion, opposite attraction
